I have my personal beliefs regarding the supernatural, but I tend to be more skeptical and science-based first before I assume something is supernatural. From my understanding, science is based on the observable world and as someone else said, the material world. That is, through observing, questioning and testing something that is seemingly tangible. It is through this process that we discover things about the universe and our world. Science is what got us out of the dark ages so to say and made life a bit easier as in the case of discovering and synthesizing chemicals to produce medications, studying diseases in order to find medications or cures for them, etc.
Religion is basically an institution that usually is fear-based and most of the modern world is moving away from fear based dogmas and seeking out other spiritual paths for personal enlightenment. Atheism is a lack of beliefs so they don't have a set doctrine or dogma to "preach" to others and also, not all scientists are atheists, there are many who are in various scientific field that have beliefs in a God or some other deity. Some might even see the awe in things such as cells, celestial bodies, chemistry etc and it reinforces their belief in a Higher Power, however, in conducting studies, they must check their personal beliefs at the store and focus on what can be observed or the hypothesis that they are testing and so forth, in order to not contaminate their studies with personal bias.
Otherwise, this AE guy is pretty damn amusing.
